Description

Hi , I have been trying to make some headaway on this for hours now but I guess I am just tapped out on ideas.
I installed mpich2 on vista, and on command prompt I was trying to run some programs with the statement mpiexec -n 2 cpi.exe and I get the error message " Credentials for LadyBug? rejected connection to LadyBug?
Aborting: Unable to connect to LadyBug?"
I switched off everything connected to user accounts, firewalls etc.

Please help!

Hi,

Most likely the username/password registered with mpiexec (mpiexec prompts for username/password when you run it the first time OR when you register the username/password explicitly) is not correct.
Try the following and let us know if it works for you,

# Remove any registered username/password using the "-remove" option of the mpiexec command (mpiexec -remove).
# Register your username/password using the "-register" option of the mpiexec command (mpiexec -register) . Make sure that you enter the domain name if your account is a domain account.
# Validate that your username/password is valid using the "-validate" option of the mpiexec command (mpiexec -validate).
# Now run your program with mpiexec (mpiexec -n 2 cpi.exe)
